@utkarsh-garg25 I think the question has error.

@utkarsh-garg25 Total yearly investment of Jatinder = (20000*4)+(16000*5)+(10000*3)=190000. For this investment, he is getting 19000 profit. Hence,...

@khatri_me 22nd: 3s+5t=750. First solution will be, s=0, t=150. Now, value of t will go down by 3 (which is coefficent of s) for every next solutio...

@richa-malhotra (x-8)^2 + (y-0)^2 = (x-0)^2 +(y-6)^2 = (x-0)^2 + (y-10)^2. Solving this, you get 4x-3y = 7 and y = 8. Hence, x = 7.75.

A is the answer, sorry for the error. (1/2)*10*5=25.

C is the answer. y = |x+a| is a modulus graph. It will change the position, based on the value of 'a', but not the shape. It is a V-shaped graph, that...

What is the explanation for the (3^8 - 3 × 1)/3! + 1?

If you do this, there is one case where you have chosen BOTH the queens in your selection. As per the question, you should have ONE queen and ONE blac...

Assume B = Speed of a boat in still water, and C = Speed of current. 12/(B-C) - 4 = 12/(B+C) and 12/(2B-C) - 1/2 = 12/(2B+C) Solving, this, we g...

If I start at 12 noon, I will reach Pune by 430 pm i.e. in 4.5 hours. I will pass trains that left Pune at 8 am, 9 am, 10 am, 11 am, 12 noon, 1 pm, 2 ...

Speed is reducing by 1/4th, hence the time will be increased by 1/3rd. This increase is given to be 2.5 hours. => 1/3 of the actual time = 2.5 hour...
